Description:

The Atmel®AVR® ATmega8A is a low-power CMOS 8-bit microcontroller based on the AVR RISC architecture. By executing powerful instructions in a single clock cycle, the ATmega8A achieves throughput's approaching 1MIPS per MHz, allowing the system designer to optimize power consumption versus processing speed.

Features:

• Operating Voltage: 4.5V to 5V.

• Advanced RISC Architecture.

• 32 x 8 General Purpose Working Registers.

• Fully Static Operation.

• Up to 16 MIPS Throughput at 16 MHz.

• On-chip 2-cycle Multiplier.

• High Endurance Non-volatile Memory segments.

• 8 Kbytes of In-System Self-programmable Flash program memory.

• 512 Bytes EEPROM.

• 1 Kbyte Internal SRAM.

• Write/Erase Cycles: 10,000 Flash/100,000 EEPROM.

• Data retention: 20 years at 85°C/100 years at 25°C(1).

• Optional Boot Code Section with Independent Lock Bits.

• In-System Programming by On-chip Boot Program.

• True Read-While-Write Operation.

• Programming Lock for Software Security.

• Extensive On-chip Debug Support.

• 8 Single-ended Channels.

• Byte-oriented Two-wire Serial Interface.

• Programmable Serial USART.

• Master/Slave SPI Serial Interface.

• Programmable Watchdog Timer with Separate On-chip Oscillator.
